Example Provisioning Direction from the Server
The following figure shows an example NOTIFY message from the server, directing the units to perform
provisioning. The text "check-sync" is specified for "

Secure Provisioning Methods
In order to perform provisioning securely, there are 2 methods for transferring configuration files securely
between the unit and the server.
Which method is used depends on the environment and equipment available from the phone system.
Method 1: Transferring Encrypted Configuration Files
A
B
CFG_FILE_KEY2
CFG_FILE_KEY2
A.
Unencrypted configuration file
B.
Encrypted configuration file
To use this method, an encryption key is required to encrypt and decrypt the configuration files. A preset
encryption key unique to each unit, an encryption key set by your phone system dealer/service provider,
etc., is used for the encryption. When the unit downloads an encrypted configuration file, it will decrypt the
file using the same encryption key, and then configure the settings automatically.
Method 2: Transferring Configuration Files Using HTTPS
This method uses SSL, which is commonly used on the Internet, to transfer configuration files between the
unit and server. For more secure communication, you can use a root certificate.
Notice
•
To avoid redundant data transfer over the network, important data, such as the encryption key used to
encrypt the configuration files and the root certificate for SSL, should be configured through pre-
provisioning as much as possible.
